Be it known'that I, O'rro It. MILKina "citizen of the United States ofAmerica,

.and resident of Holyoke, in the county of Ha-mpden, and State ofMassachusetts, have "inventedcertain new and useful Improvei merits inHinges, of which the following is a full, clear, and exact description.

Thisinvention relates to improvements 1n hinges and of a kind especiallyadapted for employment where the projection of hinge ear pleces orprotuberances will be avoided at the junction of the hinged parts; but,on

the other hand, whereby the surface at such hinged'parts will be flushand continuous.

A hingesu'ch as exemplified by this invention is especially desirablefor use on sewing machine tables of a kind known as 1 drop top tables,that is, tables constructed .with a main top and a supplemental tophinged thereto, the sewing machine being mounted on a support within alarge aperture in the main top and adapted, whenithe. supplemental topis overturned, to lie horizontally on the main top to be automat1callycaused to descend into the said aperture and be concealed by thesupplemental top.

a In tablesvfor sewing machines of the character just above referred to,and in, many other tables having one top section hinged to another, itis very desirable that when while table top sections are in theirextended relations, and in thesame plane, there shall be no projectionor obstruction above such plane to interfere with the free moving offabrics on the table or to otherwise constitute an undesirable factor.

This inventionconsists in a hinge having 1 parts in combination andarrangement substantially ashereinafter described in con-- and set forthin the claims.

In the drawings 'Figui-e 1 is a plan view showing my improved hinge asconnecting the two parts or sections of a table top;

junction with the accompany ng drawings Fig. 2 is a vertical sectionalview on. line 2--2, Fig. 1, with the parts in extended relations; Fig. 3is a'sectional view similar to Fig. 2, but showing the arts infolded-over relations; Fig. l is an e ge view of Fi 3; Fig 5 is aerspective viewof the pa1r of hinge plates inverted; Fig. 6 is aperspeotive view of the pair of pivotally' connected link bars shownnverted.

In the (ire ings,-A A re resent a pair or set of ljkdihinge platesesigned to be Specification of Letters Patent. Application filed June30,1909. Serial No. 505,171;

clearly shown in Fig. 5.

C G represent a pair of link bars having laterally extendingtrunnion-like lugs f at their outer or most separated ends which areengaged in the said fulcrum recesses; and these link bars have at theirinner ends matching upstanding ear pieces or lugs g g d d within theirrear edges,-these recesses being most and g united by the transversepivot pin h.

The combined bulk of the ear pieces is such as to substantially fill thesaid opposed recesses a, a of the hinge plates, and their upper edgesare flatyas shown at i, so as to constitute a surface continuation whenthe parts of the hinge are in the relations shown in Fig. 2, flush withthe top of the frame plates. 5

The aforementioned lugs Z) 6, which have the fulcrum recesses (Z d inthe rear edges thereof,-are longitudinally continued in parallelism forthe entire length of each frame plate so as to make adownwardl openingchannel, the side. walls of whic constitute a guide for eaclrlink barand strengthen the hinge construction as a whole.

j 7' represent spiral springs which are preferably provided for coactionwith the link bars for exerting a pressure thereagainst to force themtoward the hinge plates A.

m and m representlips or flanges pro: jecting more o nlcss transverselyfrom the lower surfaces of the link bars and extendin transverselyacrossthe entire widths thereof ad acent the r plvotally connectedears,- these members an and m serving, when the hinge is doubled up asshown in Figs. 3 andfl, as guards to prevent the entrance of dirt intothe channel-like openings inthe hinges,

which, in the absence of these guards, would the hinged parts areopened. in the relation shown in Figs, 1 and 2 will'engage under theedge portions of the stationary hinge plate at either side of therecesses therein for preventing any possibility of upward movement ofthe hinge connected leaf relatively to the table top even although apressure from underneath might be exerted against the hinged leaf.

I claim 1. In a hinge, in combination, a pair of edgewise matchingframe-plates having opposed recesses within their matching edgeportions, a pair of link bars fulcrumed to the frame plates, havingtheir inner ends pivotally united one to the other, and comprisingmeans, adjacent their uniting pivot for substantially filling saidopposed resesses, and constituting a surface continuation flush with thetop of the frame plates.

2. In a hinge, in combination, a pair of edgewise matching frame-plateshaving opposed recesses within their matchin r edge portions, a pair oflink bars fulcrume to the frame plates, having their inner endspivotally united, one to the other, comprising means, adjacent theiruniting pivot for sub 'stantially filling said opposed recesses andconstituting a surface continuation flush with the top of the frameplates, and springs,

' under the link bars, for forcing the latter toward the frame plates.

3. In a hinge, in combination, a pair of edgewise matching frame-plateshaving 0pposed recesses within their matching edge ortions, a pair oflink bars fulcrunied to the rame plates at points remote from thematching edges of the latter having at their inner ends matching earpieces pivotally united, said ear pieces havin acombined bulk tosubstantially fill sai opposed recesses, andhaving their upperportions'tlat to constitute a surface continuation flush with the top ofthe frame plates.

4. In a hin' e, in combination, a pair of 'edgewise matc ing frameplates having opposed recesses within their adjacent edges and eachhaving remote from such edges opposed depending lugs having fu l crumresaid oppose continuation flush with the top of the frame cesses withinthe rear edges thereof, a pair of -link bars having trunnion-like lugsat. their outer ends engaged in said fulcrum recesses,

having their inner ends pivotally connected together and constructedwith parts to substantialy fill the opposed recesses in. the frameplate.

5. Ina hinge, in combination, a pair of edgewise matching frame plateshaving opposed recesses within their matching edge portions and adaptedto be litted in edgewise opening mortises. in the arts to be hingeconnected, a pair of linli bars fulcrumed to the frame plates, ,havingtheir inner ends pivotally united one to the other, formed with portionsadjacent their unitin pivot for substantially hlling said opposedrecesses and making a flush surface continuation of the frame plates andsaid link bars having at their under portions and adjacent theirconnecting pivot downwardly extended transverse ribs for formingclosures for the edgewise opening mortises when the hinge connectedparts are in folded relations.

6. In a hinge, in combination, a pair of edgewise matching frame platesto be sccured to the parts to be hinge connected, said plateshaving'opposed recesses within their matching edge portions and the edgeof one of said plates having anextension for engaging under the otherfor preventing a movement, in an upward direction, of the one laterelatively to the other, a pair of link hars fulcrunicd to thefraineplates having their inner ends ivotally united one to the otherand comprising ortions adjacent their uniting pivots for su stantiallyfilling recesses, constituting a Surface plates.
